Tonight = Stamps and Study Vocab (no other hw)

1.) STAMPS ARE DUE! If you didn't have them today be sure you have them ready tomorrow! 

• What do I do?
• Gather all your stamps. You are literally looking for a red stamp, not a paper titled "stamp." 
• Somehow fasten/get all your stamps together
• Clip them all together
• Put them all in an envelope or folder
• Some students cut out the stamps and glue them to a piece of paper or put them in a baggie
• You can do whatever works for you!
• Count all your stamps. Count them again.
• Write the total and your name on the front of your stamp.
• Double check your count.
• I will randomly select 5 names from each class and re-count these peoples' stamps; if your total is incorrect you will be given a 0.
• You must do this outside of class. If you count/gather your stamps in class you will be given a 0. 

2.) VOCAB QUIZ TOMORROW! STUDY! Here's your vocab list....

• Residual
• Formula: How it it calculated?
• Graphical Definition: What does it look like on a scatterplot (how could we draw a residual?)
• What is it? What does a residual measure? (Think about how it's interpreted)
• Overestimate
• Know what it is, how it relates to residuals
• Underestimate 
• Know what it is, how it relates to residuals
• Interpret Slope
• Interpret Y Intercept
• Interpret R^2
• Compare Correlations (like #9 from our ch. 7 vocab quiz)
• Actual Value (y)
• Predicted Value (y-hat)
• What does "best fit" mean? (think "least squares")
• How do we check: "is a linear model appopriate?" (3 things)
• Coefficient of Determination (what is that?)

3.) This textbook HW is due Friday (get a head start so you can enjoy Halloween!)

• Pages 214-  : 7, 9ce, 11, 13, 15a, 
• For #11 you need to answer questions 1, 3, 4 for each scatterplot
• You probably can't do all of 11, but you probably could comment on the effect on correlation...
• You can definitely do 7, 9ce, and probably 13, and 15a
• Want more review for our test?
• Do all of #9!
• Do 15cde
